Across
- 1. the amount of space an object takes up
- 4. a force that also means perpendicular
- 6. the state of being stretched tight
- 8. When one object Exerts a force on a second, the second object exerts and equal and opposite force back on the first
- 11. the force of attraction between all masses in the universe; especially the attraction of the earth's mass for bodies near its surface
- 14. a force that involves no direct contact between two objects
- 15. when the forces pushing (or pulling) an object in one direction are the same size as the forces acting in the opposite direction
- 16. when the forces pushing (or pulling) an object in one direction are a different size as the forces acting in the opposite direction
- 18. the unit used to measure force
- 19. a force that acts at the point of contact between two objects
Down
- 2. a person or thing that takes an active role from a force
- 3. a change that is a result of a force
- 4. Objects will not change their velocity unless an unbalanced force acts on them
- 5. a push or pull upon an object resulting from the object's interaction with another object
- 7. is the force exerted by a surface as an object moves across it or makes an effort to move across it
- 9. a person or thing that receives an active role from a force
- 10. the heaviness of a person or thing
- 12. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object)
- 13. a force in which something is stretched or compressed
- 17. An objects tendency not to change its velocity
